The Hennessey HPE750 Camaro ZL1 Lays Down 661/695 (Video)

We frequently highlight new high performance packages from tuning companies for vehicles like the new Chevrolet Camaro ZL1 but today, we bring you a video showing the Hennessey HPE750 tuning package in action on the dyno – lifting the output of the supercharged Camaro to 661 rear wheel horsepower and 695lb-ft of torque.

The 6th generation Chevrolet Camaro ZL1 is the most powerful factory-built Camaro ever, with the supercharged LT4 offering 650 horsepower and 650lb-ft of torque at the crankshaft. We previously featured a video of a stock 2017 Camaro ZL1 on the dyno in Houston, making 554 horsepower and 532lb-ft of torque at the rear wheels with the manual transmission, so the newest ZL1 makes almost as much horsepower at the wheels as the previous generation did at the crankshaft (580bhp in the 5g ZL1).

Although the newest Camaro ZL1 is the most powerful factory-built GM muscle car ever, there is always someone faster, and that is where aftermarket tuning companies like Hennessey come into play. Last year, we discussed the Hennessey HPE750 upgrade for the new Camaro ZL1, which lifts the engine output to 750bhp. Today, we bring you a look at that HPE750 package in action on the dyno, as the results are pretty impressive.

Hennessey HPE750 Camaro ZL1 Dyno Run
In the video below, a 2017 Chevrolet Camaro ZL1 fitted with the Hennessey HPE750 package stretches its legs on the dyno. This package adds a cold air induction, unique ECU tuning, long tube stainless steel headers, a new lower pulley and a belt upgrade - resulting in 12 pounds of boost pressure. As was the case with the stock ZL1 on the dyno a few months back, this car is fitted with the manual transmission.

We get to watch and listen from a few different camera angles as Hennessey makes a hard dyno run with the new Camaro ZL1, each angle offering a different sound. From the rear, we hear the exhaust roar. From the front, we hear a combination of the blower whine and the exhaust. From closer to the engine bay, it is all blower and induction noise and from the driver’s side window – it is a mix of all of the various sounds.

This Camaro ZL1 sounds amazing from every angle, so when watching the video, make sure to have your speakers turned up. Don’t worry if your coworkers are within earshot – it sounds so good that everyone will enjoy hearing it. (Note: I am kidding – do not actually blast this video at work because I suggested that you can.)

At the end of the video, the camera swings over to the dyno screen for a look at the numbers for this Camaro ZL1 – and they are good. With the addition of the HPE750 package, this Camaro laid down 661 horsepower and 695lb-ft of torque at the rear wheels. Compared to the other Camaro ZL1 we featured in stock form, this Hennessey-tuned Camaro offers more than a hundred extra horsepower with more than 130lb-ft of torque.

Those are great numbers and Camaro ZL1 owners who opt for this package will have a far better chance of beating the guy down the street with the Hellcat Challenger.
